“Ambassador Kiplagat in particular should be further questioned, given his role in the Washington Trip theory as well as his more recent involvement with the Sunguh Committee and the allegation he provided misinformation,” the TJRC report states.

According to detectives from Scotland Yard, Kiplagat told Ouko’s sister Dorothy Randiak that Biwott had a serious falling out with Ouko during a US trip in January 1990.

“Randiak said Kiplagat told her there was a serious disagreement between Ouko and Biwott on the Washington Trip, that all was not well between the two, and that Ouko had flown back separately from the rest of the Kenyan delegation,” the TJRC says

A delegation of 84 Kenyans was on an unofficial visit to the US National Prayer Breakfast with President George H W Bush and other world leaders when differences emerged between Ouko and Biwott.

“Since it was not considered an official state visit, President Daniel Moi was unable to get a private audience with the President of the United States. Ouko led a press conference and also met with some human rights organisations and US representatives on Capitol Hill,” the report says.

Quoting a report by Scotland Yard, the TJRC report said Ouko privately met Bush in the absence of the Kenyan delegation, which made close Moi associates, including Biwott, very jittery.

Nkaissery was also accused of gross human rights violations by TJRC in connection with the 1984 military operation in West Pokot county, Operation Nyundo.

Nkaissery, then an army major, is among senior military officers the commission accused of gross human rights violations, including torture, sexual violence and murder.

“In some cases, security agents starved animals, approximately 30,000 cattle, that had been confiscated, as a way of compelling their owners into surrendering guns,” the report states.

It recommended Nkaissery be investigated and possibly prosecuted for his role in the controversial operation.

Kariuki was separately put on the spot by TJRC for yet another massacre in Northeastern.

Although he denied knowledge of any deaths and rape in the 1980 Karatasi/Garissa Gubai Massacre, the report says Kariuki bears responsibility for the operation and ensuing atrocities, together with former Provincial Commissioner Benson Kaaria.

“The Commission finds the conduct of Benson Kaaria and GG Kariuki, both of whom appeared before the Commission, is consistent with official denials and deflections,” the commissioners concluded.

The violence occurred when government forces, saying they were flushing out gangster Abdi Madobe, set fire to Bulla Karatasi village, killing residents and raping women.

Then, they forcefully interned the populace at Garissa Primary School football pitch for three days without water or food, resulting in over 3,000 deaths.
